  • Rapid detection of E. coli cells in urine samples using a ...

    Escherichia coli is one of the main causes of urinary tract infections (UTIs). E. coli is commonly detected from urine using standard culture method. However, the urine sampling and analysis required for these methods can be costly, time consuming (requires 24 to 48 hours) and labor-intensive. This …

  • Urine Culture with E. Coli: Meaning, Results and

    2021-7-29 · The presence of E. coli in urine usually indicates a urinary tract infection, but it may not always cause visible symptoms. When symptoms appear, they may include a burning sensation while urinating, a strong urge to urinate, passing small amounts of urine, passing strong-smelling urine, and urine that appears cloudy or red.

    In this study, as expected, E. coli was not exclusively associated with contamination of urine, but E. coli was dominant in urines from patients diagnosed with a UTI. Enterococci were more prevalent in contaminated urines than UTI positive urines. Contamination of the urine with both E. coli and enterococci is almost certainly via faeces. In contrast, coagulase-negative staphylococci, part of normal skin flora, …
